I'm building a flywheel in a vacuum (for reduced friction) and want a
brushless motor to drive the thing at about 25,000 RPM. Power consumption
should be about 6-10 watts. I've considered the brushless DC motors 
for RC airplanes, but they seem bigger (.75 pound with controller) and 
more powerful than necessary. Any suggestions? This is a constant-speed application, so an AC motor is a possibility if the efficiency is good.

	Thanks, Ben
